Minor Moves: Valdez, Graham, Iribarren, Morales, Jackson, Hensley

Righty Jose Valdez has inked a minor league contract with the Red Sox. The 30-year-old has seen 24 big league games with the Astros, but worked last year at Triple-A, putting up a 5.72 ERA in 39 1/3 innings. Valdez has shown the ability to miss bats (career 8.7 K/9), but also tends to miss spots (5.2 BB/9).

Tyler Graham, a 29-year-old outfielder, has signed a minor league deal with the Giants. Graham spent all of 2006-11 with the San Francisco organization, then split 2012 between the Giants and Diamondbacks. He got a cup of coffee with the D-Backs (two plate appearances), but ended up out of the MLB structure thereafter. Last year, he bounced between four Independent and Mexican League clubs. In his last full Triple-A season, 2011, Graham posted a .273/.337/.338 line with 60 stolen bases.

The Reds have signed a minor league deal with second baseman Hernan Iribarren. The 29-year-old Venezuelan received 29 plate appearances over 2008-09 but has yet to return. Last year, with the Rockies' Triple-A affiliate, Iribarren slashed .312/.367/.407 in 286 plate appearances.

Outfielder Angel Morales has reached agreement on a minor league contract with the Marlins. The 2007 third-round pick had spent his entire career with the Twins organization, reaching the Double-A level last year at age 23. Morales earned the promotion with a .297/.364/.525 start to the year in 234 High-A plate appearances, but failed to follow up in the penultimate level of the minors (.169/.230/.307 in 184 plate appearances).

The Nationals have signed southpaw Zach Jackson to a minor league deal. Now 30, Jackson saw 105 1/3 innings over the 2006-09 period after being drafted in the first round of the 2004 amateur draft. Jackson has bounced around the league, failing to stick as a starter. Last year, after converting full-time to relief for the Royals, he pitched to a 1.32 ERA in 41 innings at Double-A and Triple-A. Jackson managed a sturdy 2.57 K:BB ratio in 2013, but did so on the back of just 4.0 K/9 (against a career-low 1.5 BB/9).

Washington also signed righty Clay Hensley to a minor league deal with a Spring Training invite, MLB.com's Bill Ladson reports on Twitter. The 34-year-old last saw MLB time in 2012 with the Giants, when he had a 4.62 ERA over 50 2/3 innings of relief. Over his career, Hensley has started 49 big league games and appeared in over 200 others out of the pen. He threw to a 2.57 ERA in 35 Triple-A innings last year with Reds and Brewers affiliates, registering 9.8 K/9 against 4.9 BB/9 in the process.
